Project Description

GE Global Research, GE Energy, and the University of Pennsylvania will model creep-fatigue-environment interactions in steam turbine rotor materials for advanced ultra supercritical coal power plants. The work will demonstrate computational algorithms for alloy property predictions and to determine and model key mechanisms contributing to the damages of creep-fatigue-environment interactions.

Project Benefits

This project will enable more accurate prediction of long service life of advanced alloys for AUSC power plants These advancements will enable faster materials design and implementation and better producibility of large scale components. Improvement to high-temperature advanced-materials will promote the development of advanced power plant designs that can operate at higher temperatures and pressures, leading to higher efficiency and operational flexibility and resulting in lower capital and operating costs.
